As a professional agent your REALTOR should perform a comprehensive market analysis on your home. This price analysis should include recent sold comparable, any pending like properties and your current listed competition. Doing this takes in all the factors effecting the price and marketability of your home. Your professional agent should also make adjustments for factors such as location, square footage and number of bedrooms and bathrooms as well as other important differences. The professional agent should present this analysis to you in writing and go over the comparables and adjustments with you. If your agent does not take the time to do a full, true market analysis then hire a professional who will.
